Abstract
It is shown in the paper that the interaction of highly oriented graphite flakes and graphene films with alkanes is a necessary but insufficient condition for observing the Josephson current-voltage characteristics in them, which is known to be inherent in all superconducting materials. Another key factor is the creation of a deformation field in the graphene material.
